PM5000 Modbus update rate via Ethernet

[suzuki-takahir_1]

Hello everyone,

Our customer would like to read real time current and power values at high speed update rate of PM5000's Ethernet (Modbus TCP) by their PLC etc. (PM5320, PM5560 etc.)

It seems that PM5500 updates the measurement values every 1 seconds by its specification.

 ("The meter provides highly accurate 1-second measurements." by PM5500 User manual HRB1684301-12)

However I couldn't find Modbus update rate in the specification.

Therefore please inform the following specification if someone knows?

1) PM5500's Modbus update rate via Ethernet (Modbus TCP)

2) PM5300's measurement update rate and Modbus update rate via Ethernet (Modbus TCP)

Our customer will be happy to get the updated value every 1 second via Modbus TCP.

Thank you.

Hello @suzuki-takahir_1 

The Modbus update rate for PM5500, PM5300 series meters is 1 second. 

The response in TCP or Serial RS485 (PM5300) will be less than a second, but the value will be same for the period of 1 second and it will get update in next second.
